Dear Collaborators,

Feb 27 - day shift: During this shift we have 3.5 hours of 'good' production data with RF on, FFB on, fast feedforward off.

Feb 27 - swing shift: we have completerd pedestal runs for 40Ca, 208Pb-4 targets for transverse polarization measurement.
Performed PITA scan.
Tried fast feedback with fast feedforward on. It worked (https://logbooks.jlab.org/entry/3793526).
Around 19:30 there was problem on 1L07 cavity(https://logbooks.jlab.org/entry/3793466). MCC recovered from it and send beam into the hall around 10 pm.
During the calibration run with C-1% target MCC faced problem with the 1L17-7 cavity and was not able to deliver beam into the hall.
We haven't acquired any Coulomb from this shift.

Feb 28 - Owl Shift: No beam till 6:00 O'clock in the morning due to 1L17-7 cavity recovery.
Started production for the last half hour of this shift. Beam was not stable!!

Feb 28 - Day Shift: 8:30 - 10 : MCC will perform software test for the EasyButton for faster and safer beam recovery from trips.
After that MCC will try to straighten (vertically) the beam in the Compton Chicane.
The plan is to go back to production as soon as possible.

We will have our usual meeting upstairs in the counting house at 3:15 PM today. Bluejeans link for remote participants: https://bluejeans.com/256205934
